SPECIFICATION forming part of Letters Patent No. 302,913, dated August5, 1884.

Application filed January 2l, 1884.

To all whom t may concern:

Beit known that I, IsAAe KIRK, of Warren, in the county of Trumbull andState of Ohio, have invented certain new and useful Improvements inHeating Apparatus, of which the following is a specification.

These improvements relate to house-heating apparatus; and theyconsist'in the combi nation, with the customary iiregrate used indwellings, of a water-back composed of water-chambers and a system ofwater-pipes connected by pipes to a suitable water-tank from above, andan arrangement of radiating-pipes located below said grate, from whichheated air may be obtained, and which may be conveyed away to heat otherapartments. The object of this is to utilize the intense heat in theback and jambs of a fire-grate which heretoiore has gone to waste.

In the drawings, Figure 1 is a vertical section of a fire -grate andchimney, showing three floors of a house and arrangement of pipes andwater-back in connection therewith. Fig. 2 is a sectional view ofwaterchambers forming the watenback. Fig. 3 is a horizontal sectionthrough saidwater-ehambers and side j ambs. Fig. et is a verticalsection, from i" ront, through the side water chambers or jambs.

A represents an ordinary brick chimney, and B a grate fireplace. Theiire in grates heats the back and jambs usually to an intense degree,which heat it is the object of my invention to utilize by employing itto heat water for warming other apartments of the house. In the back ofthe rire-place, usually lined with fire-brick, and in the sides orjambs, I provide waterchambers C D. rIhese consist of cast-iron boxes C,having partitions c, arranged to convey the water back and forth. Saidchambers are connected with cach other by pipe-connections c', as seenin Fig. 2, to form a continuous current through them. In front of thisfire-back I also provide a coil of water-pipe, E, for a like purpose tothat of the chambers. The lower chamber, C, and lower coil, E, isconnected by down pipes f f, with a coil of pipes, F, located beneaththe floor in a suitable compartment for the purpose. rIhe jamb-chambersD are also connected with the same coil, F, by pipe d. rIhe upperchamber, C, and upper coil, E, are con- (No model.)

nected by pipes G, which may be hid in the walls, and passing upward toan upper room, lead to the upper part of a tank, I-I. The top ofthe sidechambers, D, are also connected by a pipe, I, to the said tank. A pipe,J, connects the bottom of the tank with the upper branch of the coil F.By this arrangement of pipes a circulation of water is maintained fromthe tank down through the coil F, and up through the water-chambers `C Dback to the tank again, by the boiling of the water in the waterAback,jambs, and coil in the fireplace. rIhe water-chambers C have connectionsc2 with the pipes leading upward to the tank, the purpose of which is toprovide sufficient communication upward for the hot water and prevent anexcess of steam collecting or remaining in the chambers. The top of thetank is provided with an escape-pipe, p. rlhe coil F is contained in asuitable room, box, or chamber for the purpose of heating the airtherein, which may be conveyed to other rooms or apartments for warmingthem.

From the foregoing it will be seen that the surplus heat from a commonfire-grate is employed for a useful purpose-that is, for gen4 eratingheated water and heated air for supplying yheat to other and adjoiningrooms or apartments.

The grate is provided with an adjustable blower, K, which is suspendedby chains It, passing up over pulleys in the upper part of thegrate-front on the inside, the opposite ends of the chains havingcounterbalance-weights w. The blower may thus be readily raised orlowered by the use of a poker or other implement, and when up is out olthe way. This provides a very convenient means of disposing of a blower,and avoids the annoyance and difficulty of handling heated blowers.

Having described my invention, I claim- The combination, with the grate,ofthe water-chambers C D and the coil of pipe E, each connected by pipesfj' and d with the coil F below the grate, and by pipes G I with thetank II above the grate, and the tank connected withthe said coil F,substantially in the manner and for the purpose specified.

ISAAC KIRK.
